title: The complete mitochondrial genome and phylogenetic analysis of the vulnerable troglomorphic species Sinocyclocheilus anatirostris GZNU-YZ01
description: Golden-line fish genus Sinocyclocheilus (Cyprinoidea; Cyprinidae) is one of the taxa with very high species diversity among Chinese cave fishes (Ma et al., 2019), with 76 species currently recorded (Jiang et al. 2019),mainly divided into 4 species groups (S. angularis group, S. jii, S. cyphotergous, and S. tingi groups) (Zhao & Zhang, 2009).S. angularis group is the most typical species of Sinocyclocheilus adapted to cave groundwater environment, they are distributed mainly in the Red River system in Guangxi, Beipanjiang in Guizhou and Nanpanjiang in Yunnan(Lin & Luo,Liu et al.,2018), 1986.Sinocyclocheilus anatirostris appears to be characterized by loss of body color and degradation of eyes and scales in cave environments where it lives for long periods of time without light and low oxygen, while other species of the S. angularis group differ greatly in the degree of adaptation to cave environments(Wen et al 2022).The completion of mitochondrial gene sequencing of this species is beneficial in providing molecular evidence for differences in the evolutionary and adaptive characteristics of S. angularis group species.
